It appears that low light AF is improved. and several new settings are added. I don't fully understand when AF is improved though. Is it when the scene is underexposed or just when you are using a high ISO? I have tried some tests with my v1.1 firmware GH3 but it seems to do an excellent job already without the update.

Has anyone applied the update already. Will applying this update prevent you from using a Hack/Patch that is based off of the v1.1 firmware? If so then I imagine a lot of people won't update right away. I don't intend to hack my GH3 so I will give v1.2 a shot.

There is a good explanation of the low light focusing by Andy Westlake at the link below.

Here are the changes

Ver.1.2

"Low Light AF" is added that makes it possible to set focus on the subject in low-lit situations (-3EV).

"Silent Mode" is added which suppresses electronic shutter, shutter sound, operation sound and flash emission with a single setting.

"Exposure Comp. Reset" is added which resets the setting of exposure compensation to ±0 whenever the camera is turned off or the shooting mode is changed.

Performance of AF is enhanced in use with H-PS14042 and H-PS45175.

Connection problem with Apple Mac computers via Wi-Fi is fixed.
